Piggyback ECU?

[ben_r1]

Went to get a quote today from a tuning company to fit uprated cams to my car and they said about fitting a piggyback ecu...:S

Can anyone explain to me what this means, as i know you can map std ecus or get an aftermarket stand alone ecu, but have never come across this setup before.

How does it work, has anyone on here use a similar setup and what are the advantages/disadvntages?

Thanks.

2nd ECU containing a map over rides your map while it is attached but leaves the main ecu map in tact so when its removed you have your standard map left,
think blue fin

(prob wrong)

 

[ben_r1]

Is there any difference in just remapping the std ECU and getting a piggyback?

Remap the std ecu, they are just pushing their products on you.

Thats what i thought, but apparently to get full benefit out of it i need the piggyback???

No, what they are tring to say is this:

"Sorry sir, we don't know how to map your stock ECU so we are telling you this addon is the best thing since slice bread"

No you dont, Standard ecu is 100000000% times more powerful, you would only need a new ECU if your cams were super wild or you were running boddies etc

As above. Pointless. Standalone ECU's are only needed when you require the flexibilty to go out with the Std ECU parameters.

OMEX/Motec/Emerald etc.

 

[ben_r1]

Its not a standalone, they wanna fit a piggyback.

Something about the standard ECU can only be mapped within certain parameters and the piggyback will allow more flexibility.

Cams are quite mild...

Cams + RS Tuning live map = win

RS tuning = 500 mile trip = pain in the arse

Ah dont u hate it when every tuning company you go to tells you a different thing!!!

This is turning into a minefield, all i wanted was someone to fit the cams and a poxy remap to suit lol

 

[TOGUSA]

go to GDI they could prob do it all and they are quite close

 

[Johnc172]

You're in Essex, what about Mark Fish to fit them?!

As for the remap, Sanspeed in Bexleyheath done my remap, proper job of it too!

RS Tuner Pro from fast chip with wideband sensor and custom map ftw

Yep I agree, stick with standard ECU as already said they probably arn't familiar with the stock unit.

do it right first time = win

 

[powey]

for everything else theres mastercard

 

[Andyman]

What tuning company was it out of interest?

Never had my piggy running right. Thank god for ECU mapping

 

[kevo66]

Exactly as I said then TBH!!!

piggybacks are funny on modern ECUs as they have adaption, which basically changes the map as it think's there is a problem. A piggyback interferes with sensor signals to "trick" the stock ecu.
